EFFECTS OF FLOW IMPROVER ADDITIVES ON DISTILLATE FUELS FROM OIL SHALE

The ability of additives to improve the cold flow properties of shale oil distillates boiling on the diesel fuel range was evaluated using hydrotreated shale oils as model fuels. Crude oil shale from Occidental Shale Company was fractionated to give three liquids in the diesel fuel boiling range. Each fraction was hydrotreated to three different severities to afford nine different model fuels. A variety of commercial and experimental additives were evaluated as cold flow improvers in these fuels at treat levels of 0.04 wt.% to 0.4 wt.%. Both the standard pour point test (ASTM D97) and a more severe low temperature flow test were employed. Reductions in pour points of from zero to 70 degrees F and improvements in a low temperature flow test from zero to 16 degrees F were achieved. It is concluded that these additives can play an important role in improving the cold flow properties of future synthetic fuels of the diesel type derived from oil shale.
